[0:06] <t3chguy> Berg: without additional components you can only use it as a Digital sensor
[0:06] <t3chguy> so I don't see whats hard about code checking gpio high/low
[0:06] <Berg> i only want to set it to detect on off
[0:06] <Berg> im not sure about the voltage
[0:06] <t3chguy> not sure?
[0:06] <Berg> if it runs on 3 v
[0:06] * taza (~taza@unaffiliated/taza) Quit ()
[0:07] <Berg> yeah
[0:07] <t3chguy> it'll output the same potential as vin
[0:07] <t3chguy> so if you power it at 3v3 then DO HIGH will be 3v3
[0:07] * makaveli0227TL (~makaveli0@ has joined #raspberrypi
[0:07] <Berg> ok good
[0:08] <Berg> thank and code to look at the pin if high or low is all i need then
[0:08] * Hix (~hix@97e0a23c.skybroadband.com) has joined #raspberrypi
[0:09] <Berg> i only need to check the DO pin?
[0:09] <t3chguy> yes
[0:09] <t3chguy> the AO pin is an analog output
[0:09] <Berg> excellent i was a bit lost
[0:09] <Berg> thanks
[0:10] <t3chguy> I have a similar module but it has a microphone instead

[0:11] <t3chguy> guessing you don't want to mod the charger
[0:11] <Berg> is funny?
[0:11] <Berg> not at all
[0:11] <t3chguy> fair enough
[0:11] <Berg> i want to keep units seperater
[0:12] <t3chguy> you could just use an optodiode on its own or LDR+Resistor potential divider
[0:12] <Berg> well i have these photodiode
[0:12] <Berg> having is good

[0:38] <Jacruth> Hello, I have setup an static ip for the wlan0 interface in my raspberry pi: http://paste.debian.net/366084 - However, it is not being setup when reboot: http://paste.debian.net/366086/
[0:41] <[Saint]> Jacruth: does your router support DHCP Reservation lists?
[0:41] <[Saint]> Infinitely easier and more versatile than static addressing.
[0:42] <Jacruth> well, in fact I'm trying yo setup an access point (hostapd), so I hope that the Rpi will be the router
[0:45] <meiamsome> so you need to start hostapd on startup?
[0:46] <Jacruth> I am starting it, but the problem is that the DHCP doesn't work because the iface doesn't have a proper ip
[0:46] * Jezz (Jezz@ has left #raspberrypi
[0:47] <meiamsome> What DHCP server are you using?

[0:51] <Jacruth> do you think that I should reserve and assign a fixed ip?
[0:53] <meiamsome> Jacruth: I see some people have had issues with hostapd and isc-dhcp, suggesting dnsmasq, which I have had success with personally before
[0:53] <meiamsome> if that's an option

[1:02] <meiamsome> Jacruth: it does have a dhcp server in it, not sure if the dns is disableable if that's a problem though

[3:22] <merrick`> Tenkawa, it has a temp censor for the cpu
[3:22] <Tenkawa> hmmm
[3:23] <Tenkawa> do you know which module/sys/proc control reads it?
[3:23] <Tenkawa> lm-sensors isnt finding it on a standard scan
[3:23] <[Saint]> echo -n "CPU Temperature (C): " ; cat /sys/class/thermal/thermal_zone0/temp | cut -c1-2
[3:23] <Tenkawa> [Saint]: thanks
[3:23] <merrick`> lemme seeeee
[3:23] <[Saint]> inadvertently answered your question, lol
[3:24] <[Saint]> that's a string I use for pumping out a nicely formatted CPU temp report.
[3:24] <[Saint]> but it also coincidentally answers your question.
[3:24] <[Saint]> /sys/class/thermal/thermal_zone0/temp
[3:24] <Tenkawa> very nice
[3:24] <Tenkawa> whats a "safe temp" anyway?
[3:25] <[Saint]> anything under 85C, really. EVen that is well within safety limits.
[3:25] <[Saint]> But that's where it'll shut itself down.
[3:25] <merrick`> looks like whatever scripts i hacked together, uses vcgencmd, but does something similar to what saints does.
[3:25] * Coldblackice (~anonz@unaffiliated/coldblackice) Quit (Read error: Connection reset by peer)
[3:25] <[Saint]> It'll throttle at 80C IIRC.
[3:26] <Tenkawa> k so 33 is plenty low
[3:26] <[Saint]> basically, you'll never have to worry about the temperature, like...ever.
[3:26] <[Saint]> unless you live in the Sahara or so.
[3:27] <merrick`> even then, it'll just power down.
[3:27] <merrick`> i guess you could still cook it technically.
[3:27] <Tenkawa> I'm running 900 arm freq, 500 core freq, 500 sdram freq, so i didnt want to melt it
[3:27] * spybert (~spybert@c-50-173-18-125.hsd1.ca.comcast.net) Quit (Quit: Leaving)
[3:27] <merrick`> takeaways from todays lesson: don't live in an oven, or near the sun.
[3:28] <[Saint]> Tenkawa: that's nothing stressful at all really.
[3:28] <Tenkawa> oh good
[3:28] <Tenkawa> I really like this unit
[3:28] <Tenkawa> I really need to get more of them

[3:30] * spybert (~spybert@c-50-173-18-125.hsd1.ca.comcast.net) has joined #raspberrypi
[3:31] <[Saint]> Oh, if you want that to be more easily accessible - you can do "echo 'alias cpu-temp='echo -n "CPU Temperature (C): " ; cat /sys/class/thermal/thermal_zone0/temp | cut -c1-2'' >> ~/.bash_aliases" or add it to .bash_aliases manually.
[3:32] <[Saint]> then it'll be accessible as the command 'cpu-temp'
[3:32] <Tenkawa> meh I just created a temp script that ran a cat and cut on that device node
[3:32] <Tenkawa> works fine enough for me
[3:32] <[Saint]> here's a similar one for cpu-freq
[3:32] <[Saint]> alias cpu-freq='echo -n "CPU Frequency (Hz): " ; cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq'
[3:32] * heskew (~textual@ Quit (Quit: My Mac has gone to sleep. ZZZzzz…)
[3:33] <Tenkawa> cpufreq-info already works great for that
[3:33] <[Saint]> that would mean installing it on my end. ;)
[3:33] <Tenkawa> ahhh

[3:37] <[Saint]> Or, as I now like to call it "Making Me Scream At My Monitor-erer"
[3:38] <ppq> is the movie worth the time watching it?
[3:38] <[Saint]> s/movie/series/
[3:38] <[Saint]> and, yes. I consider it so.

[3:38] <ppq> oh it's a series
[3:39] <[Saint]> Massively frustrating and infuriating.
[3:39] <[Saint]> But, great.
[3:39] <ppq> good to know

[5:18] <[Saint]> any pi distro that targets ARMv6 should work
[5:18] <raspberrypifan> is there a list
[5:18] <raspberrypifan> smeone make me a list
[5:19] <raspberrypifan> i used to run raspbx on the original pi
[5:19] <speakquietly> Maybe backerypi can make one and then sell it to you
[5:19] <raspberrypifan> ill send u 5 for the pi
[5:21] <[Saint]> raspbian, ALARM, OpenElec, RiscOS, etc. etc. etc.
[5:21] <[Saint]> Literally any pi distro that can target ARMv6, so pretty much everything except Snappy, Win10, Mate.
[5:21] <backerypi> not Mate?
[5:22] * yumaokao (~yumaokao@218-161-54-18.HINET-IP.hinet.net) Quit (Ping timeout: 256 seconds)
[5:22] <[Saint]> No.
[5:22] <raspberrypifan> so raspbx should work
[5:22] <raspberrypifan> http://www.raspberry-asterisk.org/
[5:22] <[Saint]> Ubuntu Mate relies on ARMv7 (Pi 2) arch.
[5:22] <backerypi> oh sorry the zero
[5:23] <[Saint]> I'm aware.
[5:23] <[Saint]> The zero uses ARM11/ARMv6
[5:23] <backerypi> its sort of irrelevant what os you run
[5:23] <[Saint]> No, it isn't.
[5:23] <raspberrypifan> how is it that its v6 but also 11 at the same time
[5:23] <[Saint]> Depending on the use case, or if you want it to actually be able to run at all, it;s very relevant.
[5:24] <backerypi> they can each be dockerized
[5:25] <[Saint]> ARM11 is just another name for ARMv6
[5:25] <backerypi> and you can fuck up as much as you want in there
[5:25] <[Saint]> Just as ARM Cortex-A|M* is another name for ARMv7
[5:25] <raspberrypifan> oh is it
[5:25] <raspberrypifan> oh docker still confuses me
[5:25] <raspberrypifan> idont get it
[5:26] * Syliss (~Home2@c-24-23-6-50.hsd1.ca.comcast.net) Quit (Quit: Syliss)
[5:26] <speakquietly> same.
[5:26] <[Saint]> docker isn't going to magically make an ARMv6 host boost an ARMv7 image, either, FWIW.
[5:26] <[Saint]> so it's not entirely relevant or correct to say "can be dockerized".
[5:26] <Xark> [Saint]: Minor quibble, not all Cortex-Mx processors support all operating modes (e.g., M0 is Thumb2 only IIRC).
[5:27] <raspberrypifan> getting to complex now
[5:27] <backerypi> well no i meant whatever families work on that particular arm
[5:27] <[Saint]> Xark: yeah, I probably should've specified M3/4, but, * was ...less keys.
[5:27] <[Saint]> lol
[5:28] <raspberrypifan> my arm?
[5:28] <backerypi> zero or pi2 arm
[5:29] <[Saint]> There's probably a family of parasitic mites living on your arm, but, I can't vouch for their current employment status.
[5:29] <raspberrypifan> lol

[5:29] <raspberrypifan> my arms are itchy

[6:11] <Hitechcg> idk how many hubs do that - I had a (cheap) USB card reader/powered USB hub that could, and a small mini USB hub that couldn't (probably a diode).
[6:12] <Hitechcg> Anyways, backfeeding is not recommended, as there's no protection circuitry going backwards from USB. I'd recommend against it, anyways.

[6:56] <Hitechcg> (actually only like 10 though)
[6:56] <merrick`> I just picked up a beginners learn to solder kit. Figured I'd practice before I risk burning up anything worthwhile. (RE: "soldering skillz")
[6:56] * dreamon (~dreamon@unaffiliated/dreamon) has joined #raspberrypi
[6:57] <Hitechcg> The problem here is just that our soldering iron is awful
[6:58] <merrick`> kit comes with a shitty one i'm assuming, i'll practice with a crap one so if/when i move up it'll be easy i figure
[6:58] <Hitechcg> Although I haven't soldered much, so I haven't really practiced, I've used other irons, and it's much easier to solder with those
[6:58] <merrick`> until then i'll stick with a bread board and leds and stuff
[6:58] <Hitechcg> I prefer breadboards
[6:59] <merrick`> I was at microcenter today and just browsing around, so many things that require soldering i figured i'd pick up the $20 starter kit and learn
[6:59] <Hitechcg> I don't know what iron your kit came with but NO DON'T try to teach yourself with it

[7:00] <Hitechcg> raspberrypifan, Android won't really run /well/ on any Pi at all
[7:00] <merrick`> raspberrypifan, pretty sure only really old android versions have ARM processor ports iirc
[7:00] <raspberrypifan> isnt android arm based?
[7:01] <Hitechcg> merrick`, this soldering iron is just old and has a bent tip
[7:01] <merrick`> ah i see, that could be a problem yeah hah
[7:01] <Hitechcg> But it's REALLY frustrating to try to use
[7:01] <Hitechcg> (it's not just the tip though)
[7:02] <merrick`> raspberrypifan, looks like i'm mistaken, here's a youtube vid of lollipop running on a pi 2 https://www.youtube.com/watch?v=aSgQDhM84Ko
[7:02] <Hitechcg> But if the one with the kit works fine, then feel free to use it
[7:03] <merrick`> i've soldered like twice in my life. I'm assuming those were crap soldering irons as well so i'll give it a shot.
[7:03] <merrick`> if i screw up the $20 kit...oh well, that's why i got it

[7:25] <Eternias> hi
[7:26] <Eternias> anyone have experience with GPIO and raspberry pi?
[7:27] <AiGreek> a little ...
[7:27] <sir_galahad_ad> a bit why?
[7:29] <Eternias> i am first getting into it
[7:29] <Eternias> trying to make an LED light up
[7:29] <sir_galahad_ad> ok how far have you gotten?
[7:29] <Eternias> looks simple, use resistor, use LED
[7:29] <Eternias> i got it to light up
[7:29] <sir_galahad_ad> pretty much
[7:29] <Eternias> my question is...
[7:29] <Eternias> with LED, there is a "long" end and a short end
[7:30] <Eternias> if I were to "reverse" the LED so that the long end goes where the short end was
[7:30] <Eternias> vice versa
[7:30] <sir_galahad_ad> it won't light
[7:30] <Eternias> do bad things happen like the LED shorts out or something?
[7:30] <Eternias> and also... does the direction of the resistor matter?
[7:30] <sir_galahad_ad> possibly but most likely it just won't work
[7:30] <sir_galahad_ad> resistor direction does not matter
[7:30] <Eternias> okay cool
[7:31] <Eternias> do you guys typically keep your Pi on when you do these kinds of connections
[7:31] <Eternias> or do you keep it off?
[7:31] <Eternias> then turn it on only after you finish?
[7:31] <AiGreek> i always keep it on
[7:31] <Eternias> cool
[7:31] <sir_galahad_ad> i tend too keep it on but leaving it off is probably technically safer
[7:31] <Eternias> i read a tutorial that said to "keep your pi off when trying to do any connections so you dont short anything out"
[7:32] <Eternias> when connecting jumpers
[7:32] * ozzzy_ (~ozzzy@unaffiliated/ozzzy) has joined #raspberrypi
[7:32] <Eternias> but glad its safe to ignore
[7:32] <sir_galahad_ad> welll....
[7:32] <sir_galahad_ad> sort mostly safe
[7:33] <AiGreek> i'm not agree with that but ...meh, why not
[7:34] <Eternias> okay
[7:34] <Eternias> do any of you guys do robotics?
[7:34] <sir_galahad_ad> accently poke your LED with a 5v lead when you meant to use a 3.3 you could fry the LED...i don't think you can hurt the pi with it's own voltage but i'm pretty new at this
[7:34] * vdamewood (~vdamewood@unaffiliated/vdamewood) has joined #raspberrypi
[7:35] <Eternias> that is good to know, so make sure when joining jumper wire from PI to breadboard.. do not connect to 5v accidentally
[7:36] * ozzzy (~ozzzy@unaffiliated/ozzzy) Quit (Ping timeout: 276 seconds)
[7:37] <Eternias> im thinking about trying to use it with arduino
[7:37] <Eternias> and trying to get some setup where I can use PI to issue commands to arduino
[7:37] <Eternias> to communicate to a motor controller
[7:37] <Eternias> to spin a motor (attached to a wheel)

[7:44] <Eternias> anyone know
[7:44] <Eternias> how I can operate my PI on an external battery
[7:44] <Eternias> without reliance on the "microusb plug to wall"?
[7:47] <chesty> Eternias: you need 5 volts and playing it safe, 2 amps, how you get that is irrelevant
[7:48] <AiGreek> You can even go up to 3A
[7:48] <chesty> if you have a 12 volt battery, you can use a car cigarette usb charger
[7:48] <Eternias> so your saying if I get a battery pack, doesnt matter triple A's double A's rectangular batteries
[7:48] <Eternias> its all the same
[7:48] <Eternias> as long as you have 5 volks with 2 amps
[7:49] <chesty> Eternias: exactly
[7:49] <chesty> you can get boost circuits that bump a voltage up to 5 volts, say from 3.7 of a lithium ion
[7:50] <chesty> or you can get buck circuits that drop the voltage down to 5 volts from, say, 12 volt car battery

[7:54] <Eternias> this is great
[7:55] <Eternias> so given my current LED example
[7:55] <Eternias> i can just use the appropriate power
[7:55] <Eternias> and not have to change any of it
[7:55] <Eternias> so..... out of curiosity
[7:55] <Eternias> i want to attach an Arduino
[7:55] <Eternias> and I want to attach it to a Motor Controller that uses maybe 40 watts
[7:55] <Eternias> if i stick with wall charger
[7:56] <Eternias> i don't have to really "do anything extra" right?
[7:56] <Eternias> nothing will short out?
[7:56] <Eternias> (i just want to be extra careful)

[7:59] <Eternias> ok bad question
[7:59] <chesty> i'm not sure Eternias, i believe arduino's gpio is 5v, and the pi is 3.3v, so i don't know if you can connect them together without extra circuits
[8:00] <Eternias> are there any guides on connecting such batteries/boost circuits?
[8:00] <Eternias> these are new concepts to me
[8:00] <Eternias> and buck circuits

[8:10] <Eternias> based on the video
[8:10] <sir_galahad_ad> ugh when you think you did something wrong but it's a bad LED....
[8:10] <Eternias> it looks like I can just plug the arduino via USB into the Pu
[8:10] <Eternias> anand the Pi2 can just power it
[8:10] <Eternias> lol bad LEDs are annoying

[14:05] <treaki__> hi
[14:05] <TandyUK> ok, so how about a suplier that stocks it all :P
[14:05] <treaki__> i need to setup wifi on my pi
[14:06] <giddles> in germany i get a shitty DC supply, a crappy case and a gn standart wlan
[14:06] <giddles> :D
[14:06] <giddles> no not n
[14:06] <giddles> i mean the slow one
[14:06] <TandyUK> b? lol
[14:06] <giddles> i feel like the sherrif of nottingham robbed me
[14:07] <giddles> my dealer here is such a bitch, to save transport cost or whatever he dont send manual with
[14:08] <TandyUK> well tbh the first project is just a prototype, s for that id be happy with a bundle, as long as it comes with all the manuals etc :P

[14:08] <TandyUK> but i agree when we actually build the final system we dont want any shitty components
[14:08] <giddles> well i payed around 70 euro for all
[14:09] <giddles> you may need a wlan stick, a closed case, a DC supply and a micro sdcard :P
[14:09] <giddles> i can send you my shitty one :D
[14:09] <TandyUK> no way wlan is going anywhere near it ;)
[14:09] <TandyUK> and case is irrelevant, as this will be part of a larger system
[14:09] <chesty> i got mine plus accessories from ebay, but you have to shop around. sometimes there's a pi markup.
[14:09] * mlelstv fortunately didn't buy a rpi because it is cheap
[14:10] <TandyUK> cost matter very little too tbh
[14:10] <giddles> 79eur per rpi is cheap?
[14:10] <giddles> :)
[14:10] <giddles> i got now 9 or 10
[14:10] <giddles> i dont knew ;D
[14:10] <TandyUK> a good qulity bit of hardware is what im after :P
[14:10] <giddles> the dc supply should be oki dok
[14:10] <giddles> get for an b2 the 2.5a ones
[14:11] <TandyUK> dc psu will be seperate too tbh long term
[14:11] <giddles> no problem connecting usb things
[14:11] <giddles> :)
[14:11] <TandyUK> i'll be drivign 2x rpi's and various other components, to be switched by the relay boards

[14:12] <giddles> :D

[17:20] <Luyin> I'm trying to reinstall sonic-pi now, because apt tells me it's damaged and ought to be reinstalled before removal. but when I try, apt hangs completely, not doing anything anymore.

[18:43] <sir_galahad_ad> vikaton: i dont know :(
[18:43] <sir_galahad_ad> Hello sprocket
[18:43] <vikaton> :(
[18:43] <sprocket> quick question regarding the wiringPi library - has it been updated to support RPi2’s?
[18:43] <vikaton> Ive seen both implementations
[18:43] * RebelCoder (~Yuriy@ has left #raspberrypi
[18:43] <vikaton> sprocket: I believe so
[18:43] <vikaton> I used wiringPi on my rPi 2
[18:43] <sir_galahad_ad> sprocket: afaik rpi2 is exactly the same as far as gpio no?
[18:44] <Chillum> Nice! I put my Pi Zero with wifi dongle on a 10000mAh(advertised value, probably 2/3 that) usb battery bank and it is on its 25th hour now, still 35% left on battery
[18:44] <vikaton> sir_galahad_ad: rPi2 has a different GPIO base address
[18:44] <vikaton> but thats the only difference
[18:44] <sprocket> sir_galahad_ad - i thought that rpi2’s had a 40pin gpio
[18:44] <sir_galahad_ad> sprocket: they do, but so do the rpi A+ and B+
[18:44] <sprocket> sir_galahad_ad - and that rpi1’s had fewer pins
[18:44] <sprocket> ah, ok
[18:44] <sprocket> newbie questions here, thanks :)
[18:45] <vikaton> rPi2 has a base of 0x3F000000
[18:45] <vikaton> rPi has a base of 0x2000000 i believe
[18:46] <Chillum> the pi 2 only gets 6 hours uptime on the same setup
[18:47] <sir_galahad_ad> Chillum: awesome
[18:47] <vikaton> well, doesnt the pi2 use alot more resources?
[18:47] <Chillum> very happy with the low power usage of the zero
[18:47] <Chillum> though without wifi it consumes so little power my battery bank turns off
[18:48] <Chillum> measuring on my multimeter the wifi doubles the power consumption of an idle pi

[19:01] <Chillum> if I get 26 hours on a 10500mAh battery then I should be able to run it for 2 hours from a tiny little 800mAh battery like they use on toy helicopters. I am going to make a shield with a boost converter and 800mAh battery and try to keep it in the form factor of the zero
[19:03] <TandyUK> Hix: suggest the sd card is dead/dying imho
[19:04] <Roonix> What were you doing for those 26 hours? Was that idle or being used or what?

[21:36] <Berg> yes
[21:36] <gordonDrogon> it sort of suggests it's a digital output so shouldn't need a pull up/down.
[21:37] <gordonDrogon> however if you have wiringPi installed, then try : gpio mode $pin up
[21:37] <Berg> im get the code from the pi and paste one sec
[21:37] <gordonDrogon> or where $pin is the wiringPi pin number, or; gpio -g mode $bcm_gpio_pin up
[21:37] <jjham> It probably needs a pull up resistor.

[21:40] <gordonDrogon> just checle - the lm393 that it's using is an open collector output, so yes - enable the internal pull-up and it'll work better.
[21:41] <The_Borg> <----berg http://pastebin.com/fYAcPKEJ
[21:41] <Berg> hmm
[21:42] <Berg> so i should set the pin every time?
[21:42] <Berg> before i test?
[21:42] <gordonDrogon> easy to just get wiringPi and do it from the command line than to write a program - for testing, anyway.
[21:42] <gordonDrogon> you only need to set the pull-up/down once per reboot.
[21:42] <jjham> What pin are you looking at?
[21:42] <Berg> see paste
[21:42] <jjham> There is a AO and a DO?

[21:52] <jjham> gordonDrogon: I understand that. As an Electronic Engineer, it's quit confusing to deal with your library that tries to lay the Adriano pins on the Pi.
[21:52] <gordonDrogon> jjham, it's made 1000's of arduino users happy though.
[21:53] <jjham> I'm sure it has, but mad may RPi users confused.
[21:53] <gordonDrogon> and it doesn't force it on you - you have the choice of 3 different schemes.
[21:53] <jjham> I understand that.
[21:53] <jjham> But it's the first best choice for getting to the GPIO ports.
[21:53] <gordonDrogon> it does have the small advantage that the wiringPi pin numbers didn't change when they did a board revision on the Pi and changed 3 pins ...

[22:13] * tchan (~tchan@lunar-linux/developer/tchan) has joined #raspberrypi
[22:13] <gordonDrogon> the schmatic shows a resistor + led conneced between the 3.3v supply and the DO pin - which is connected to the comparitor which is an open-collector output.
[22:14] <gordonDrogon> so my approach would be to test the module with just power alone - no data connection. Get it to a state where you can shine a totch on it & get the DO led to light, then go off when you remove the torch.
[22:15] <The_Borg> so use the DO pin on pin 15?
[22:15] <gordonDrogon> then once you get that going, connect it to the Pi.
[22:15] <The_Borg> ok be a while
[22:15] <The_Borg> thanks
[22:15] <gordonDrogon> and here is the confusion that jjham talks of - what pin to connect it to. Use the command: gpio readall to get a visual diagram of the gpio connector.
[22:16] <gordonDrogon> the physical board pins are the ones in the very middle.
[22:16] <jjham> The Pi has no analog input pins. Only digital pins.
[22:16] <gordonDrogon> yes, so we use the DO pin on the module - which is a digital output.
[22:17] * arnoue (~aaron@ has joined #raspberrypi
[22:17] <gordonDrogon> but get the module working first with just power before connecting it to the Pi.
[22:17] <t3chguy> wait what

[22:18] <jjham> Didn't I bring this 1/2 hour ago?
[22:18] <jjham> Yeah I shocked too!
[22:18] <gordonDrogon> t3chguy, wiringPi pin numbers.
[22:18] <t3chguy> wow
[22:19] <t3chguy> I should say
[22:19] <t3chguy> I've not yet had chance to use WiringPi
[22:19] <t3chguy> but will install it momentarily
[22:19] <t3chguy> to see what you mean by a visual diagram
[22:19] <gordonDrogon> other things too, but they're not important here. If you stick your nose out far enough in just anbout anything people will complain....
[22:20] <ali1234> gpio readall?

[22:20] <ali1234> it needs a compute module mode that you can force to run on any pi
[22:20] <gordonDrogon> or at least it did have - I admit I've not fired up my CM for some time.

[22:21] <gordonDrogon> when wiringPi detects its on a CM it only works with native bcm_gpio pin numbers.
[22:21] <ali1234> sure
[22:22] <ali1234> i just want it to dump every BCM pin from 0-53, in order, regardless of what pi i run it on
[22:22] <ali1234> in the end i wrote my own

[22:23] <jjham> Then what's the problem, it you have your own solution?
[22:23] <ali1234> i did try to adapt wiringpi to do this but i couldn't understand how it maps the numbers and whatever i tried it just crashed with segfaults
[22:23] <gordonDrogon> ali1234, it's all done in the gpio program.
[22:23] <ali1234> well, i didn't release my tool, so it's of no benefit to anybody else
[22:23] <ali1234> yes i know
[22:23] <ali1234> i specifically tried to adapt gpio

[22:25] <gordonDrogon> in native mode there is no mapping.
[22:25] <gordonDrogon> it's marginally faster than any other mode.
[22:25] <ali1234> "native" mode?
[22:25] <jjham> ali1234: Are you using the BCM manual???
[22:25] <ali1234> jjham: using?
[22:25] <gordonDrogon> with the -g flag, or wiringPiSetupGpio() ;
[22:26] <gordonDrogon> as a hack, if you patched readall.c to always call cmReadall() then it should do what you want.
[22:26] <ali1234> i tried that, it doesn't list everything

[22:33] <promet> Hi, I'm starting vnc server on my pi with a 1920x1080 resolution. when I connect, the resulting x window is the right size, but the pi video resolution of occupies a much smaller resolution within this window. Does anyone know a fix for this?
[22:33] <ali1234> i'm not even allowed to reporet bugs now?
[22:33] <gordonDrogon> jjham, I'm ok with someone else doing similar - actually, looks like I have some bugs here - checking now.
[22:33] <gordonDrogon> trouble is, I think no-one is actually using CMs... or if they are who knows what they're using on it...
[22:33] <promet> I'm giving the -geometry parameter on the command line, might this need to be in a conf file? This is xtightvncserver, bte
[22:33] <ali1234> i'm not using a CM either
[22:34] <promet> bte = btw
[22:34] <ali1234> i just needed a full dump of the pins
[22:34] <ali1234> including ones not on the header
[22:34] <gordonDrogon> I'm on a Pi2.
[22:34] <ali1234> me too
[22:34] <ali1234> your dump seems correct except for 52-55
[22:34] <ali1234> not sure what's going on there
[22:35] <gordonDrogon> so what's 52 & 53? they're marked 'internal' on the manual.
[22:35] <ali1234> i have i2c and spi enabled, which accounts for the differences
[22:35] <ali1234> they are part of the on-board SD card slot

[22:59] * LemonjuiceX (AdiIRC@ Quit (Ping timeout: 240 seconds)
[22:59] <ali1234> that sounds right. LEDs are usually wired VCC -> LED -> GPIO

[22:59] <ali1234> as opposed to GPIO -> LED -> Ground
[23:00] * esas (~esas@unaffiliated/esas) has joined #raspberrypi
[23:00] <ali1234> it's mainly a historical thing because GPIO pins used to be able to sink more current than they can source
[23:00] <gordonDrogon> It's Vcc -> R -> LED -> open collector transistor -> 0v
[23:00] <gordonDrogon> and the output is from the LED -> collector junction -> Pi

[23:02] <Berg> its not reading the module

[23:02] <gordonDrogon> good move.
[23:04] <ali1234> the way i remember what open collector means is by remembering it's either "open" (disconnected) or "collecting" (sinking current)

[23:12] <ali1234> there are numerous ways of doing that
[23:12] <ali1234> easiest is probably to use xdg-autostart, if lxde supports it
[23:12] <OS-19702> Ok, how do the media center OS's typically do it?
[23:13] <OS-19702> i put a line in the xdg autostart file but it doesnt seem to run my python script
[23:13] <ali1234> xbmc does it by not being an X application and entirely taking over the display
[23:13] <ali1234> sorry, kodi
[23:13] * Chillum (~highinbc@unaffiliated/chillum) has joined #raspberrypi
[23:14] <ali1234> pygame can do this, but i think you'll lose acceleration since it uses SDL which only has an fbdev driver, and not SDL2 which i think has a dispmanx driver
[23:15] <gordonDrogon> Berg, well - at least you found out now. just need to test these things in steps, 1 at a time rather than jump in and write code...
[23:15] <gordonDrogon> ali1234, yes, thanks.
[23:16] <gordonDrogon> must update my basic interpreter to use sdl2... one day...
[23:16] <ali1234> it's very easy... SDL2 is about a million times better
[23:16] <ali1234> actually there's a guide
[23:16] <ali1234> https://wiki.libsdl.org/MigrationGuide
[23:16] <gordonDrogon> yea, I started reading it... ran out of time.
[23:17] <Berg> yeah i agree with you gordonDrogon but you try and tell my excited kid type brain to do the steps
[23:17] <OS-19702> Is there a guide you can point me to, to start writing Raspberry PI GUI's?
[23:17] <gordonDrogon> the down-side is that I'd then need to ship all the sdl2 libraries with it.
[23:17] <Berg> :)
[23:17] <ali1234> OS-19702: what type of GUI do you want to make?
[23:17] <Berg> still fun
[23:17] <gordonDrogon> Berg, I know... all part of the learning experience though!
[23:18] <ali1234> raspbian has SDL2 no?
[23:18] <OS-19702> it would be nice to boot run into say a custom built weather app instead of the desktop
[23:18] <Berg> I tell my granson that too but hay ....
[23:18] <Berg> hehehe
